Mazda CX-5 Service & Repair Manual: Engine Tune Up

Engine Tune-up Preparation

NOTE:

1. Connect the M-MDS to the DLC-2.

2. Shift the selector lever (ATX) or shift lever (MTX) to the following position:

NOTE:

3. Run the engine speed at a constant 2,500 to 3,000 rpm

and warm up the engine (engine coolant temperature: 80 °C {176 °F}

or more, oil temperature: 60 °C {140 °F}

or more).

4. Turn off all electrical loads with the engine idling.

5. If the cooling fan is operating, wait until is stops.

Idle Speed Inspection

NOTE:

1. Complete the engine tune-up preparation..

2. Verify that the idle speed (M-MDS PID: RPM) is within the specification using the PID/data monitor function of the M-MDS..

Ignition Timing Inspection

NOTE:

1. Complete the engine tune-up preparation..

2. Verify the ignition timing (M-MDS PID: SPARKADV) using the PID/data monitor function of the M-MDS..

3. Verify that ignition timing advances when the engine speed increases gradually.

Idle Mixture Inspection

1. Verify that the idle speed and ignition timing are within the specification..

2. Insert an exhaust gas analyzer into the tailpipe.

3. Verify that the CO and HC concentrations are within regulation.

Idle-up Speed Control Inspection

NOTE:

1. Complete the engine tune-up preparation..

2. Verify that the idle speed according to each load (M-MDS PID: RPM) is within the specification using the PID/data monitor function of the M-MDS (except idle speed decrease after applying load)..

Fuel Tank Removal/Installation
WARNING: Fuel is very flammable liquid. If fuel spills or leaks from the pressurized fuel system, it will cause serious injury or death and facility breakage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line Safety Procedure”, while referring ...

ABS Control
Outline ABS control occurs when wheel slip is determined by the DSC CM (based on the four ABS wheel-speed sensors). Then, the DSC HU inlet and outlet solenoid valves are operated and brake fluid pressure is controlled accordingly to prevent wheel lock-up. Feature Use of ...
